16387-70-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16387-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,3,8 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16387-70:
(7*1)+(6*6)+(5*3)+(4*8)+(3*7)+(2*7)+(1*0)=125
125 % 10 = 5
So 16387-70-5 is a valid CAS Registry Number.

A procedure for the oxidative 'dimerization' of aliphatic 1-alkynes

Brandsma,Verkruijsse,Walda

, p. 137 - 139 (1991)

Aliphatic 1-alkynes RC≡CH (R = alkyl) are readily converted into diynes RC≡CC≡CR, by introducing oxygen into a mixture of the acetylene and pyridine using copper(I)bromide as a catalyst and 1,8-diazabicyclo[5.4.0] undec-7-ene as a co-catalyst.

UTILIZATION OF "BIS(TRIPHENYLPHOSPHINE)PALLADIUM" AS CATALYST IN THE CROSS COUPLING REACTION OF TERMINAL ACETYLENES WITH ALKENYL HALIDES

Champs, F.,Chamorro, E.,Gasol, V.,Guerrero, A.

, p. 3211 - 3220 (2007/10/02)

Utilization of the 14-electron species "bis(triphenylphosphine)palladium (0)" as catalyst has been extended to the cross coupling reaction of a terminal acetylene with an alkenyl halide to prepare conjugated enynes, such as (Z)-11-hexadecen-13-ynyl acetate 1, which are direct precursors of Z,Z and Z,E dienyc unsaturated systems.
